Figure 9-5 shows the backup process of a client that deduplicates its own data.
The destination is a PureDisk storage pool. A description follows.

The following list describes the backup process for a deduplication client to a media server deduplication pool:
■The NetBackup Job Manager (nbjm) starts the Backup/Restore Manager (bpbrm) on a media server.
■The Backup / Restore Manager probes the client to determine if it is configured and ready for deduplication.
■If the client is ready, the Backup/Restore Manager starts the following processes: The OpenStorage proxy server (nbostpxy) on the client and the data moving processes (bpbkar on the client and bptm on the media server). NetBackup uses the proxy
■The Backup/Archive Manager (bpbkar) generates the backup images and moves them to the client nbostpxy process by shared memory.
